Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). These iron ores have been mined to produce almost every iron and ...
Jan 12, 2020· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

Iron Ore. India is one of the few countries of the world which is endowed with vast reserves of good quality of iron ore. She possesses over 20 % of the world's total reserves. The quality of Indian ore is very high with iron content of above 60 %. Most of the iron ore found in the country is of three types- haematite, magnetite, and limonite.
Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and a good supply of oxygen (provided by a bellows .
While some operations float at a natural pH, at least in roughing, in these cases the combination of reagent selection and relative pyrite floatability is controllable. Even when neutral pH is used in roughing, the cleaner flotation stages are generally conducted at higher pH to ensure iron sulphide depression.
